“Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: ‘Ye must have faith.’”

The quantum hypothesis will eventually find its exact expression in certain equations which will be a more exact formulation of the law of causality.

It was not by accident that the greatest thinkers of all ages were deeply religious souls.

There can never be any real opposition between religion and science; for the one is the complement of the other.

Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are a part of the mystery that we are trying to solve.

A scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die and a new generation grows up that is familiar with it.

There is no matter as such—mind is the matrix of all matter.

I regard consciousness as fundamental. I regard matter as a derivative of consciousness.

The pioneer scientist must have “a vivid intuitive imagination, for new ideas are not generated by deduction, but by artistically creative imagination.”

Science advances funeral by funeral.

An experiment is a question which science poses to Nature and a measurement is the recording of Nature’s answer.

The entire world we apprehend through our senses is no more than a tiny fragment in the vastness of Nature.

Every advance in knowledge brings us face to face with the mystery of our own being.

What seems today inconceivable will appear one day, from a higher stand point, quite simple and harmonious.

Religion belongs to the realm that is inviolable before the law of causation and therefore closed to science.

The man who cannot occasionally imagine events and conditions of existence that are contrary to the causal principle as he knows it will never enrich his science by the addition of a new idea.

It is not the possession of truth, but the success which attends the seeking after it, that enriches the seeker and brings happiness to him.
